Application filed December 7, 1926. Serial No. 158,063.

This inventionrelates to calendars andhas particular reference to that class of calendars which are spoken of commonly in the trade as perpetual.

Among the objects of the invention is to provide a mechanical calender having the adaptability of indicating as a result of a simpleadjustment the day of the week of any date desired, within the range of the machine or device, it being my purpose for the range of the device to be sufficiently extensive to cover practically any historical date.

Another object of the invention is to pro vide a calendar in the nature of an indicator that may be readily adjusted iior any desired year or years and for the monthly and weekly indications to be availed ofwith the least amount of inconvenience, and for the devices to beso set or locked. as tobe rendered foolproof and hence possessed of the highest degree of reliability, Without which acalendar would be useless.

With the foregoing and other objects in view the invention consists inthe arrangement and combination of parts hereinafter described and claimed and while the invention is not restricted to theexact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a vertical transverse section showing the interior of the device.

Figs. 6 and 7 considered together indicate the year plates located at the bottom of the casing. p

Fig; 8 is a. detail view of the adjustment mechanism for the indicators.

Referring now more specifically to the drawings I show my" improvement as com.- prising a casing 1 having asubstantiallyflat inclined face portion and a curved or :ogees shaped rear portion and mounted upon a base 16 having feet in the the nature of rubber cushions'or the like shown sti l, the casing being secured to the base by means of tap screws 37 co operating with-lugs60. se-v cured to or'extending downward from the casing. While the several arts of the device may be made of any suita le materials,-it is preferable that the casing be made of sheet metal or other strongrelatively thin material and for the'base to'be made of a. slab. of woodor its equivalent. a i a The front portion ofthe casing is provided with av large sight or window 39 of rectangular form and at the upper left and right corners are smaller openings or windows 40'and 41 for the observation respectively of the names ofthe months and the numbers ofthe months and the number of days there 1n. legend Month 42, and over the window 41 is printed the legend No Mo Days 43. Fitted within the window or sight 39 is a slide 2 within which is formed a rectangular opening or window 66 corresponding to a monthly calendar block and having a length equivalent to seven unitscorresponding to the seven days of the week indicatedat 15 in the usual form S M T? T F S marked upon the rim of theslide 2 just above the window 66. Below the window 66 and centrally of the slide is formed a pointer or indicator 44, the purpose of which will soon appear. The length of the window 39 is in; dicatcd as of thirteen unitsas compared with the seven units of the length of the window 66. i

The slide 2 is adapted to be adjusted from Over the window 40 is. printed the time to time lengthwise of the device or to the right or left as viewed in Fig. 5 by any suitable mechanism manually operated. For this purpose I indicate a threaded rod or screw 3 journaled at its ends 35 and to the ends of the outer casing 1 against; movement longitudinally of said rod, and running on the rod 3 is a threaded nut or sleeve 3 fixed, as shown in Fig, 8, to the inner surface of the slide 2 just below the opening 66, so that when the rod 3 is rotated, the sleeve 3", and consequently the slide 2 is caused to move transversely of the machine toward the left or right, according to the direction of rotation of said rod. An auxiliary indicator 12 is secured to the sleeve 3" or any other suitable portion of the slide 2 and extends downward therefrom into and along a slot 38 formed in the base 16. This indicator 12 co-operates with a transparent plate 13 of glass or its equivalent fixed in the bottom of the base adjacent to a pair of scheduled plates 5 and 6. The slide 2 is guided for its adjustments along a pair of guide ways or keepers 24 and 25 at the upper and lower edges thereof, the same being secured within the front of the main casing in any inconspicuous position. One end of the rod 3 is provided with a socket 53 for an adjusting, instrument such as a key 54 for the rotation thereof which determines the right or left adjustment of the plate or slide 2.

One purpose of the slide 2, with its indicaters 12 and 44, is to indicate the number of any selected year, whether current or otherwise. A plate 4 fixed upon the front of the main casing 1 carries in seven vertical groups or rows blocks of yearly numbers from 1900 to 2000, both common and leap years, said rows or groups of yearly numbers being arranged in units of width can responding precisely to the calendar block units above referred to in connection with the window 66, and as indicated in Fig. 5, while the pointer 44 is in its mid position over the central group or row of year numbers, it may be moved one, two or three units either to the right or to the left, to cover any one of the seven groups or rows of numbers in the plate 4, and when the slide 2 is so moved with its indicator 44, the window 66 is similarly moved through one, two, or three units in the same direction. The annual numbers indicated on the plates 4, 5, and 6 are complete only along the upper ends of the rows or groups, and to conserve space the hundreds and thousands digits are omitted elsewhere. It will be understood also that all the yearly numbers in any group or row willbe indicated simultaneously according to the adjustment of the pointers 12 and 44, and that the years so numbered in each group are so determined that the calendar pad adjustment for the months and days of the month will apply to each and every year of any one indicated group or vertical row of years. It will be remembered also that the indicators 12 and 44 are rigidly connected to each other as well as to the slide 2 so that not only will a group of yearly numbers be indicated on plate 4, but also on plates 5 and 6. No con fusion, however, arises from this circumstance because the number of the year under consideration will always be pointed out by one of the pointers, and the other will be disregarded. On plate or schedule 5 are indicated common and leap years from 1800 to 1,900, the numbers being arranged as before explained in seven vertical groups or rows. Schedule 6 indicates seven rows or groups of years prior to 1800, both common and leap years. These indicators illustrate the nature of the invention, but the scope of the years covered by the invention may of course be varied as may be desired, either for longer or shorter periods, or for the period to extend further than indicated, either forward or rearward. The plates 5 and 6 are shown recessed in a cavity or recess 46 formed in the bottom surface of the base 16. The plate 5 is provided with a slot or opening 45 for visibility of the index 12 therethrough and through the plate 13.

The calendar sheet is indicated at. 7 and comprises along its left margin :1 column 67 of the names of the months of both common and leap years, in the usual order, and along the right hand margin are two vertical columns (58 and 69 indicating the numbers of the months and the number of days therein respectively. The name of any month selected appears through the window 40, and the calendar block associated themwith at such time will appear through the window or opening (36, it being the next block below the block on the same level with the name of the month, this resulting from the fact that the constriu'tion is so designed, as shown in Fig. 5, that the number of the month is shown elevated above the calendar block therefor. The sheet or strip 7 is attached at its upper and lower ends to upper and lower rollers 18 and 19 having gears .20 connecting them for simultaneous rotation in opposite directions. The ends of the strip are secured to the rollers by means of wedge-shaped inserts 30 held in place by screws 57 in depressions or recesses 56 formed in the rollers. Fig. 1 indicates the direction of movement of the strip with respect to the rollers and how the strip coils upon one of the rollers simultaneously with its uncoiling from the other. The strip passes over a tube or sleeve 55 mounted on a movable rod 21 to whose ends are attached a pair of springs 22 operating along curved slots 47, the opposite ends of the springs being anchored at 62 in holes in the inner ill fill

til l semen frame That portion of the sheet 7 which is immediatelyyisihle or active is guided and held between a back plate 17: and the. face. plates. The back plate is 1 shown beat in Figs. 1 and]; and is held in placeby means or two tie rods 23 fixed in the end walls of the inner frame 31 so that. the sheet is held close to the sight openings in the front casing. The upper and lower edges of thejbacking plate 17 are shownrolled around the tie rods. The rollers. are provided with inner flanges flfi hetween which the sheet 7 operates and with outer flanges 27 which lie adjacent to the inner frame walls at: 31.- The upper roller'has a trunnion flfl with openingat end operating in a bearing .29 adjacent to which is a finger knob S for the manipulationof the rollers by spindle 59. Through the operation of the gears 20, the rotation of the upperroller in either direction will cause a simultaneous rotation of the lower roller in the opposite direction. Beneath the trunnion 29, the lower roller has "a trunnion 28, and therollers at their 0 posite ends have similar trunnions 28, each of which has bearing at. 28 in the inner frame. The-knob 8 isintended tobe key contnolledso as to prevent its being tam red withan unauthorized person.

I provi 0 also asafety appliance in the na.

ture of a hub 52st the: end of the lower roller remote from the knob 8 as shown in Figs. '1 and 5. The hub 52 has aserrated surface with which 'co-operates a similarly formed shoe 51 carried b a spring 50. This shoe is backedup. on t 1e op osite side of the spring by means of a mu tiple cam 48 mounted upon a-spindle 49. This spindle has a he socket 33 accessible from the left end of t ceasing, and upon rotation of the spindle and cam wheel 48 through one of the cams will thrust the shoe into locking contact with the hub 52 or to the position shown in Fi lwA further rotation through 60 wil releasethe shoe so as to permit the rollersto be rotated or ad- 'usted through manipulation of theknob 8. l prefer to insure that the spindle 49 shall be rotated always in 'one direction only,

and for this purpose I provide a pawl 64 and ratchet wheel '32 shown in Figs. 1 and 5. The pawl is held in place resiliently by means of a spring 63.

The inner frame 31is secured to the base by screws 36 which for the sakeof delicacy of adjustment longitudinally operate through'slots 65. y

The windows or openingsr39, 40, and 41 are preferably fitted with strong transparencies such as glass lenses 9, 10, and 11' respectively for clear visibility and to protect the casing I provide also a pen and pencil tray or rackB4.

elusive.

With the foregoing specific description of the desired year is found. For the current.

year, for instance, the pointer 44 would be found over the third column from the left or the oneheaded by the number 1909 in which group the current year is found. The knob 8 is then rotated to bring into view at the window 40 the name of the current month, the operator taking care to observe that the name of the month is selected in that portion of the strip 7 according to whether the year is a leap year or a common year. The current year being a common one, the selection will be taken from the upper end of the strip. a The proper block indieating the days of the monthwill appear inthe window 66, and in proper relation to the days o f the week S to S indicated thereover. The foregoing directions as to the manipulation of the device as a practical desk calendar will be applicable to the determining of the day-of the week of any date within the scope of the arrangement. More specifically, ii it is desired to determine the day of the week in which the Fourth of July fell during the year 1901, which was a commonyear,'the parts being unlocked or released, the operator adjusts the slide 2by rotation of'the screw 3 so as to bring the pointer over the column of year- 1y numbers headed by 1901, the sixth unit from the left on the schedule plate 4. The window 66 then discloses units 6 to 12 in The knob 8 isthen rotated so as to bring the name of the month, July, at the upper portion of the strip 7 into view at the window 40, thus bringing the monthly block,

the one below the name July, into View at quires adjustment but once for each year,

while the calendar sheet 7 requires adjustment once for each month. j For the convenience'of the user, the common and leap yearportions of the strip 7 may be distinguished from each other by different colors or shades of material or coloring applied thereto and likewisethe annual schedule plates 4, 5. and 6 may have their common and leap year portions respectively tintedor colored to correspondto the coloring of the sheet or strip 7. I wish to point outalso thattthe grouping of the year numbers in particular columns, witlra plurality of years in each column, all having the same characteristics of monthly and weekly adaptation in each column, is a matter of distinct importance and is believed to be unique with this invention. Furthermore, the arrangement of the your numbers in each column or group may obviously be varied and may either he in numerical order or otherwise as may be thought best.
